z(5z^(2)-80)-:5z(z+4)

Divide z(5z^(2)-80) by 5z(z+4)

Divide z (5z^2-80) by 5z(z+4)

Divide z(5z^2 – 80) by 5z(z + 4)

If z=e^((2pi i)/5) , then 1+z+z^(2)+z^(3)+5z^(4)+4z^(5)+4z^(6)+4z^(7)+4z^(8)+5z^(9)=

If z=e^((2pi i)/5) , then 1+z+z^(2)+z^(3)+5z^(4)+4z^(5)+4z^(6)+4z^(7)+4z^(8)+5z^(9)=

If z=e^((2pi i)/5) , then 1+z+z^(2)+z^(3)+5z^(4)+4z^(5)+4z^(6)+4z^(7)+4z^(8)+5z^(9)=

If z_(r)=cos.(2rpi)/(5)+isin.(2rpi)/(5) , r=0,1,2,3,4 , then z_(1)z_(2)z_(3)z_(4)z_(5) equals

int(3z^(3)-8z+5)/(sqrt(z^(2)-4z-7))dz=(z^(2)+az+36)sqrt(z^(2)-4z-7)+b ln|z-2+sqrt(z^(2)-4z-7)| where a,b in I and C is integretion constant,then

If z= -3 + sqrt2i , then prove that z^(4) + 5z^(3) + 8z^(2) + 7z + 4 is equal to -29
